Product Description:

The KL3052 analog input bus terminal crafted by Beckhoff is single-ended and comprises a dual-channel design. This terminal can process signals in the range of 4 mA to 20 mA. Powering the measuring transducers within the designated field, it also ensures safe transmission of isolated analog signals to the automation system. Designed for flexibility, the unit gets voltage for its sensors via the power contacts. Its input electronics remain unaffected by the supply voltage. This terminal has two sets of LEDs comprising the run LEDs and error LEDs.

A 0 V rail is used as the reference potential for precise input measurements. This device portrays an 80 Ohms internal resistance along with a diode voltage of 0.7 V. The unit has load only type current consumption for its power contacts. It has a 12-bit resolution corresponding to 4095 steps. This terminal comes equipped with power contacts. The product's process data is represented in two's complement form. This device needs proper mounting and wiring to be established for ESD protection. The unit includes components that are at risk because of electrostatic discharge. Its contacts can be touched by the user only after he/she has discharged himself/herself.

This bus terminal supports no wiring or disassembly when it is in the powered-on state. The product is fitted on the right side of the bus coupler. This device uses flat mounting connections to mount its mounting rails with a 7.5 mm height under it. The unit permits extension of up to 32 terminals or 64 terminals. Its mounting rail must have mounting points set at intervals of 5 cm.
